If we kept Korver, then he would have taken a lot of Jimmy's minutes this season. Korver > Belly as a player. But for our needs, trading Korver turned out for the best.

Brewer is trash, glad to see him go.

And Asik, letting him go was not a mistake by any means. The failed assumption is that Asik would have developed into the same player that he is in Houston, but in a Bulls uniform. Again, this is a bad assumption, because you may quickly forget that the Rockets have the best big-man coach in the NBA by a mile, and his name is Kevin McHale(and he does a hell of a lot more than teach post-up moves, like Hakeem and Ewing).
